"At KPWR (Los Angeles), our CCA transmitter would occasionally trip breakers and go off the air without any obvious cause. I had installed a PowerClamp unit at KWVE a few years earlier when they had a similar problem, so I installed one at KPWR. The PowerClamp unit solved the KPWR problem immediately. Since then, I have installed PowerClamp TVSS units at KSCA (Los Angeles) and will soon install one for KLVE (Los Angeles). I’ve made it my ‘standard operating procedure’ to install a PowerClamp unit at any transmitter site I’m responsible for."

“At KBIG (Los Angeles) we had continuing problems of our transmitters throwing breakers, unexplainable input power glitches, and a host of other power line-related problems. Ever since we installed the PowerClamp TVSS unit, our problems pretty much just went away. You can’t beat it. You just install it and forget about it. They work great.”

“For about 18 months we had a situation in which our FM transmitter would go off the air from an unexplained tripping of the main power breaker. This would happen once or twice each month. The power company could find no reason for the problem.” “Last December, we installed a PowerClamp TVSS on the power lines at the breaker box. It is now June, and we have had no reoccurrence of the problem.”

“We use a pair of Continental 816 transmitters, which use internal SCR regulators to control the screen and plate voltages. We had a continuing problem that was caused by the 3rd and 5th AC power line harmonics generated by these SCR regulators. When the voltage of one AC phase was high, the SCR regulators would kick in, generate lots of 3rd and 5th harmonics on the AC power line, which would cause the other transmitter to go off the air. The two 816s would fight each other, knocking each other off the air. When we installed a PowerClamp TVSS unit, it totally solved the problem. The PowerClamp unit attenuated the power line harmonics by about 50db, which we verified on a Fluke network analyzer. We haven’t had this problem since, and I’ll be ordering another PowerClamp when we install a new BE transmitter very soon.”

“Several months ago our Harris FM 20K transmitter began a long series of off-the-air problems. Two sets of brand new circuit breakers at the transmitter building would be tripped. With no power to the transmitter or STL, someone had to drive up to the transmitter site, reset both breakers and put the transmitter back on the air. This kept happening for nine months, sometimes 3 or 4 times a week. After exhausting every other possibility we could think of, we turned to your PowerClamp line conditioner. Since the new line conditioner was installed August 29th, KWVE’s transmitter has remained on the air without incident. Many thanks on behalf of KWVE radio and its listeners.” “Last December, we installed a PowerClamp TVSS on the power lines at the breaker box. It is now June, and we have had no reoccurrence of the problem.”

“Please consider this to be a testimonial letter regarding our use of your TVSS over the last year. Based on quality and performance, your units have done more than we expected and we would not hesitate to recommend its use to anyone.”

“The variable quality of the 120-volt AC power supplied to the TeleSat Centre has caused considerable degradation to the quality of video and audio recordings. Recently, we installed a PowerClamp unit for evaluation. This unit appears to work very well. There has been noticeable reduction in audio hum and noise, and elimination of video noise. It appears to eliminate noise created by our projector motors, dimmers, and florescent lighting, and also reduces noise generated by other hydro customers.”
